Visual Field Progression in Glaucoma During COVID-19 : Journal of Glaucoma
actors affecting progression. Methods: This hospital-based prospective cohort study included patients diagnosed with primary open angle glaucoma, primary angle closure glaucoma, and ocular hypertension who fulfilled the eligibility criteria. We included 234 eyes with at least 5 reliable Humphrey visual fields (24-2 SITA Standard) before March 24, 2020 and 2 or more after. Glaucoma Progression Analysis software was used to carry out both trend and event-based analysis. Rates of progression prepandemic and postpandemic were compared. Univariate and multivariate logistic regression analyses were done to identify factors affecting progression. Results: The rate of visual field progression increased significantly post lockdown, mean deviation (MD) prelockdown -0.1(SD:0.8) (95% CI: −0.196, 0.001) dB/year versus −0.3 (SD:0.6) (95% CI: −0.362, −0.208) dB/year post lockdown (P<0.001) and Visual Field Index(VFI) pre lockdown −0.001(SD:0.007) (95% CI: −0.002, 0) %/year versus −0.6 (SD:2.2) (95% C
